RESUMO
BACKGROUND: Chlorhexidine gluconate solution is superior to povidone-iodine for prevention of surgical site infection. However, the overall efficacy of chlorhexidine gluconate for surgical site infection prevention in various types of gastroenterological surgery, as well as the optimal concentration of chlorhexidine gluconate, remain unclear. The aim of the present study was to clarify whether subcutaneous wound soaking with chlorhexidine gluconate would reduce the incidence of surgical site infection associated with gastroenterological surgery in patients with wound classes â ¡ to â £. METHODS: Patients were randomly assigned (1:1) to either wound soaking with chlorhexidine gluconate (chlorhexidine gluconate group) or no chlorhexidine gluconate soaking (control group). After closure of the abdominal fascia, gentle subcutaneous soaking of the wound was performed using gauze fully soaked in aqueous 0.05% chlorhexidine gluconate before skin closure. Incisional surgical site infection was diagnosed using the Centers for Disease Control and Prevention criteria. The primary end point was the occurrence of incisional surgical site infection. RESULTS: Among 363 patients, 245 (67%) underwent laparoscopic surgery. All 363 patients were included-181 in the chlorhexidine gluconate group (49.9%) and 182 (50.1%) in the control group. There were no significant inter-group differences in patient background, the type of procedure, or wound classification. The incidence proportion of incisional surgical site infection was significantly lower in the chlorhexidine gluconate group than in the control group (9.4% vs 19.2%; P = .008). CONCLUSION: Subcutaneous wound soaking with chlorhexidine gluconate reduces the incidence of incisional surgical site infection in patients undergoing gastroenterological surgery.

BACKGROUND: The aim of this study was to evaluate the effectiveness of a modified reconstruction technique-anchored straight stomach reconstruction-in reducing the incidence of delayed gastric emptying (DGE) after pancreaticoduodenectomy (PD) and its impact on postoperative nutritional recovery. METHODS: A case series analysis of 125 consecutive PD patients was conducted: 104 of them had undergone anchored straight stomach reconstruction (SSR group) and the remaining 21 without (Non-SSR group). The incidence of DGE and the change in postoperative nutritional status (body weight and serum albumin level during 12 months post-surgery) were compared. RESULTS: The incidence of DGE in the SSR group (13%) was significantly lower than that in the Non-SSR group (33%) (P = .018); further the significant DGE (grade B or C) was only 5%. Comparison of nutritional status showed that SSR facilitated a prompt recovery of body weight and serum albumin level at 6 months after PD. At 12 months after surgery, body weight gain was significantly better in the SSR group than in the Non-SSR group (P = .006), and albumin level tended to be higher in the SSR group (P = .071). CONCLUSION: Straight stomach reconstruction is able to reduce DGE in patients after PD and also improves their postoperative nutritional recovery.
RESUMO
INTRODUCTION: We aimed to evaluate the safety and short-term outcomes of robotic-assisted transabdominal preperitoneal repair for inguinal hernia in 12 pioneering hospitals in Japan. METHODS: Clinical data of patients who underwent robotic-assisted transabdominal preperitoneal repair between September 1, 2016, and December 31, 2021 were collected. Primary outcome measures were intra-operative adverse events and post-operative complications, whereas secondary outcomes were surgical outcomes, including chronic pain, recurrence, and learning curve. RESULTS: In total, 307 patients were included. One case of inferior epigastric arterial injury was reported; no cases of bowel or bladder injury were reported. Thirty-five seromas were observed, including four (1.3%) cases that required aspiration. The median operative time of a unilateral case was 108 minutes (interquartile range: 89.8-125.5), and post-operative pain was rated 1 (interquartile range: 0-2) on the numerical rating scale. In complicated cases, such as recurrent inguinal hernias and robotic-assisted radical prostatectomy-associated hernias, dissection and suture were safely achieved, and no complications were observed, except for non-symptomatic seroma. All patients underwent robotic procedures, and there was no chronic post-operative inguinal pain, although one case of hernia recurrence was reported. Regarding the learning curve, plateau performance was achieved after 7-10 cases in terms of operative time (P < .001). CONCLUSION: Robotic-assisted transabdominal preperitoneal repair can be safely introduced in Japan. Regardless of the involvement of many surgeons, the mastery of robotic techniques was achieved relatively quickly. The advantage of robotic technology such as wristed instruments may expand the application of minimally invasive hernia repair for complicated cases.

Primary gallbladder neuroendocrine tumor (GB-NET) is extremely rare. Therefore, tumor behavior and adequate treatment in GB-NETs are still unclear. A 74-year-old man without any specific complaints was referred to our hospital cause of gallbladder tumor. Abdominal ultrasonography examination revealed a 22-mm non-pedunculated tumor in the gallbladder body. Contrast-enhanced computed tomography showed a polyp that was enhanced in the arterial phase. The patient underwent gallbladder bed resection and radical lymphadenectomy with a diagnosis of gallbladder carcinoma. Macroscopically, the resected specimen showed a nodular expanding tumor measuring 32×15 mm in the gallbladder body. From the pathological findings, a grade 3 GB-NET was diagnosed. Only cystic lymph node metastasis was observed. The patient was discharged uneventfully, but bone and lymph node metastasis were detected eight months after surgery. We conclude that grade 3 GB-NET shows occasionally malignant biological behavior although NET G3 is distinguished from neuroendocrine carcinoma in the current WHO 2019 classification of NET.
RESUMO
Synthetic mesh is now used for inguinal hernia repair in most cases. It is well known that the indwelling mesh contracts after placement in the body, regardless of the material. The aim of this study was to develop a method for indirect measurement of the mesh area postoperatively that allows for easy comparison with the condition of the mesh immediately after surgery. X-ray-impermeable tackers were used to fix the mesh, and changes of the indwelling mesh after surgery were measured indirectly using two mesh materials. This study involved 26 patients who underwent inguinal hernia repair with a polypropylene or polyester mesh (13 patients each). Polypropylene showed a stronger tendency to shrink, but there was no significant difference between the materials. For both materials, some patients showed relatively strong shrinkage and others showed relatively weak shrinkage. The group with the strong shrinkage had significantly higher body mass index. The results of the present study showed that mesh surly shrinked over time and there was no adverse effect of mesh shrinkage on the patients outcomes in this population. Mesh would shrink over time regardless of the sort of mesh but it did not affect the patients outcomes.

BACKGROUND: Mixed neuroendocrine carcinoma (NEC) and hepatocellular carcinoma (HCC) is extremely rare, thus radiological features have not been fully clarified. CASE: A male patient (age: 70 years) visited our hospital due to a tumor in the liver. Examination using contrast-enhanced computed tomography (CT) revealed a tumor (diameter: 5.0 cm) in hepatic segment 5, with early enhancement of the peripheral area and slight internal heterogeneous enhancement in the arterial and delayed phases, respectively. F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET)/CT revealed intratumoral heterogeneity, characterized by increased uptake (standardized uptake value, 12.10) in the corresponding low-density area detected using enhanced CT relative to the surrounding areas of the tumor. On magnetic resonance imaging, diffusion-weighted imaging also showed high intensity in the corresponding low-density area detected using CT. Preoperatively, the patient was diagnosed with HCC and underwent anterior sectionectomy. Pathological findings revealed both HCC and NEC components, and the patient was diagnosed with mixed NEC and HCC. Comparison of component distribution with FDG-PET/CT revealed an increased uptake area was congruent with the NEC component in the tumor. CONCLUSION: In this case, the difference in tumor components affected the uptake in FDG-PET/CT. Such heterogeneous uptake with an enhanced spot may be useful for suspecting the presence of mixed NEC and HCC in patients with atypical HCC.

BACKGROUND: Inguinal hernia repair is one of the most common operations performed worldwide. No consensus currently exists regarding the most appropriate operation for inguinal hernia in adolescent and young adult (AYA) patients. This study aimed to evaluate the outcomes in AYA patients undergoing high ligation or mesh repair under laparoscopy by examining the location and size of the hernia orifice defect. METHODS: We retrospectively reviewed all patients aged 15 to 40 years old who underwent laparoscopic hernia repair. Under single port laparoscopy, we classified the anatomic location (lateral, medial, or femoral) and size of the hernia orifice according to the classification by the European Hernia Society (EHS). A laparoscopic percutaneous extraperitoneal closure (LPEC) was performed on the patients with a lateral hernia with a hernia orifice defect size of ≤1.5 cm (L1). Transabdominal preperitoneal (TAPP) repair was performed on the patients with a lateral hernia with a hernia orifice defect size of >1.5 cm (L2 or 3). RESULTS: Overall, 40 patients underwent the mentioned surgical procedures. We performed LPEC on 22 patients, and TAPP on 18 patients. There were no intraoperative or postoperative complications and recurrences. CONCLUSIONS: This is the first report that evaluated the outcomes of AYA patients who underwent high ligation or mesh repair under laparoscopy by examining the location and size of the hernia orifice defect. Our data indicated that LPEC were effective and safe for AYA patients with small hernia orifice defect.

A woman in her 50s was referred to our hospital with intestinal obstruction. Ten years prior, she had been treated for gastric cancer, pathologically confirmed as stage IIIA poorly differentiated adenocarcinoma with signet-ring cell carcinoma. Intraoperatively, a 4-cm hard white tumor was found in the mesoileum and around the ileum. Pathological examination revealed poorly differentiated adenocarcinoma with signet-ring cell carcinoma and infiltration and fibrosis. Late peritoneal recurrence of gastric carcinoma was diagnosed. Recurrence of gastric carcinoma more than 10 years after curative gastrectomy is extremely rare. A review of 30 cases reported in Japan revealed recurrence was more frequent in females (60%) and the mean age was around 50 years at the time of primary surgery. Poorly differentiated adenocarcinoma and/or signet-ring cell carcinoma was the primary gastric cancer in 82% of cases and bone metastasis was the most frequent site of recurrence.

A 45-year-old woman was referred to our hospital with a huge liver tumor that had been diagnosed as a hepatic angiomyolipoma (HAML) 5 years previously. At the time of referral, it had enlarged from 12 to 20 cm within the previous 5 years and become symptomatic. Enhanced computed tomography revealed a very large, well-defined, low-density mass occupying the entire right lobe of the liver. The patient underwent right hemi-hepatectomy. The resected specimen weighed 1620 g and measured 20 × 14 × 8 cm. The pathological diagnosis was confirmed as benign HAML. The estimated growth rate of this tumor was 44% per year with a doubling time of 826 days. Although the majority of HAMLs are stable lesions, resection should perhaps be considered when the tumor is known to be growing and exceeds 6 cm in diameter, even if it has been diagnosed as benign.
RESUMO
Spindle cell type anaplastic carcinoma of the pancreas is extremely rare and has a very poor prognosis. A previously healthy 68-year-old woman was referred to our hospital due to a large tumor in the body of the pancreas. Abdominal computed tomography revealed an irregular, well-enhanced 140-mm tumor containing a cystic component. The patient underwent distal pancreatectomy for a possible malignant tumor (e.g., mucinous cystic neoplasms). Histological examination showed that the tumor contained spindle-shaped cells and adenocarcinoma with nuclear atypia, and a definitive diagnosis of anaplastic carcinoma spindle cell type was made. A review of 27 cases reported in Japan revealed 43% of these lesions invaded other organs, and 26% were classified in Stage IV at the time of diagnosis. Postoperative recurrence rate was 78.2%, and mortality rate was 59.3%. Early diagnosis and sequential radial surgery would improve the poor prognosis.

Although, free fascia lata autografts can be used to reconstruct various anatomical structures, little information is available about the status of such autografts several years after the procedure, especially in a clinical setting. Here, we describe our experience with a patient who underwent relaparotomy two years after incisional hernia repair using a fascia lata graft. A 79-year-old man underwent open hepatectomy for hepatocellular carcinoma. One year later, abdominal computed tomography revealed a locally recurrent tumor 1.5 cm in diameter and a giant incisional hernia measuring approximately 15 × 6 cm on the supraumbilical midline. After repeat hepatectomy, the incisional hernia was repaired using a free fascia lata patch as an interpositional graft. Two years later, the patient was readmitted because of recurrent tumors in the liver, and repeat hepatectomy was performed. During surgery, the fascia lata graft had survived well and become incorporated into the native fascia. We incised this fascia lata graft in the same way as for a normal laparotomy. After hepatectomy, the fascia lata graft was closed in layers with interrupted sutures. The patient was discharged on postoperative day 11 with no wound-related morbidity.
RESUMO
Perineal hernia is a type of pelvic floor hernia and an extremely rare pathologic state. Perineal hernias can be classified into anterior and posterior types according to their positional relationship to the superficial transverse perineal muscle. A 49-year-old woman presented with bulging of the right labium major while standing. Standing external ultrasonography revealed a mass in the bulge, which could not be identified by transvaginal ultrasonography, CT, or MRI. Although hernia content could not be identified preoperatively, the patient was given a diagnosis of primary perineal hernia and underwent laparoscopic repair. Symptoms resolved postoperatively, and no sign of relapse has been noted for 8 months postoperatively. Here, we report the case details and review previous case reports.

We report here an extremely rare case of hepatic sclerosing hemangioma mimicking a biliary cystadenocarcinoma. A previously healthy 39-year-old woman was referred to our hospital because of a large tumor in the liver. Abdominal computed tomography revealed early peripheral ring enhancement in the arterial phase and slight internal heterogeneous enhancement in the delayed phase. Magnetic resonance imaging revealed a tumor with low intensity in the T1-weighted image and very high intensity in the fat-saturated T2-weighted image. The patient underwent hepatectomy for a possible malignant liver tumor. Grossly, the tumor appeared as a white, solid, and cystic mass (weighted 1.1 kg and measured 170×100×80 mm) that was elastic, soft, and homogeneous with a yellowish area. Histological examination showed that the tumor mostly consisted of fibrotic areas with hyalinization. The typical histology of cavernous hemangioma was confirmed in part, and the tumor was diagnosed as a sclerosing hemangioma with predominancy of the sclerosed area. A review of 20 cases reported previously revealed that only 2 (10%) patients were diagnosed as having sclerosing hemangioma preoperatively.
RESUMO
Congenital epidermolysis bullosa is a rare, genetic condition in which even slight stimulation can cause blistering of the skin or mucosa. While previous reports of treatments requiring general anesthesia in these patients were focused on anesthesia-related procedures, such as endotracheal intubation, no report has described specific management required for these patients during surgery, such as preparation of the surgical site, fixation of infusion lines and other tubes, and adjustment of the operation table. This is probably the first report to address these issues. This report presents a case of recessive dystrophic congenital epidermolysis bullosa in which open hepatectomy was safely performed.

AIM: The indocyanine green (ICG) finger-piece method (FPM), which allows measurement of the ICG concentration by mounting a light sensor onto a finger, is used to assess liver function. We compared the ICG FPM with the conventional ICG blood sampling method (BSM) in patients with liver disorders. METHODS: Ninety consecutive patients simultaneously underwent the ICG BSM and ICG FPM. After ICG administration, blood samples were collected at 5, 10, and 15 min for the ICG BSM. The ICG concentration was measured through the finger piece by an ICG clearance meter. RESULTS: Seventy-one patients (78.9%) had Child-Pugh class A liver disease, and 19 (21.1%) had class B or C. The FPM-measured ICG plasma disappearance rate was positively correlated with the BSM-measured values (r = 0.886, P < 0.001). Bland-Altman analysis showed good agreement between the two methods (mean difference, 0.012 ± 0.018). The FPM-measured ICG plasma disappearance rate was positively correlated with the BSM-measured values both in patients with Child-Pugh class A liver disease (r = 0.821, P < 0.001) and class B or C liver disease (r = 0.859, P < 0.001). CONCLUSION: The ICG FPM may be an alternative to the ICG BSM for liver function assessment.
RESUMO
Portal vein thrombosis (PVT) is a rare but serious postoperative complication of pancreaticoduodenectomy (PD). We reported a case of late-onset postoperative PVT with hemorrhage from the common hepatic artery (CHA) in a 73-year-old man who underwent pylorus-preserving pancreaticoduodenectomy (PPPD) for duodenum papilla cancer, followed by reconstruction using the modified Child's technique. The pancreaticojejunostomy was achieved by end-to-side, 2-layer invagination anastomosis without pancreatic duct stenting. Drain removal and hospital discharge were scheduled on postoperative day (POD) 18, but blood-stained fluid in the drain and sudden hematemesis were noted. Emergency surgery was performed because PVT and imaging findings were suggestive of necrosis of the lifted jejunum. Although no jejunal necrosis was identified during surgery, bleeding from the side of the CHA was detected and the bleeding point was suture-closed to achieve hemostasis. We suspected late-onset postoperative arterial hemorrhage and subsequent hematoma formation, which caused portal vein compression and PVT formation. We chose a conservative treatment strategy for PVT, taking into account the operation time, intraoperative vital signs and blood flow in the portal vein. Despite the complicated postoperative course, he was discharged home in a fully ambulatory state on POD 167.
RESUMO
BACKGROUND/AIMS: Perioperative management of pancreaticoduodenectomy (PD) is a constant dilemma and challenging for gastrointestinal surgeons. Postoperative pancreatic fistula (POPF) and delayed gastric emptying (DGE) are of particular concern, and the onset of these conditions indicates a prolonged postoperative stay (POS). The procedure and postoperative outcomes of pancreaticojejunostomy performed at our hospital are reported. METHODOLOGY: POPF, DGE, and POS were investigated in 54 patients who had undergone PD at our hospital since June 2007. Pancreaticojejunal end-to-side anastomosis using the invagination method without a stenting tube and without duct-to-mucosa anastomosis was performed in all patients, regardless of pancreatic duct diameter. RESULTS: There were 26 patients (48.2%) without POPF, 24 (44.4%) with grade A, 4 (7.4%) with grade B, and none with grade C. The mean POS was 28.3 days. DGE was observed in 4 patients (7.4%) who underwent pylorus-preserving PD (PpPD). There were 34 patients with a soft pancreas. None of the patients experienced intraperitoneal bleeding or abscess, and no surgery-related deaths occurred. CONCLUSIONS: The reconstructive pancreaticojejunostomy procedure performed at our hospital appears to be safe and convenient, and we plan to collect additional data, including assessments of the function of the remaining pancreas, in the future.

Duplication of the alimentary tract is a rare congenital malformation that occurs most often in the abdominal region, whereas esophageal duplication cyst develops typically in the thoracic region but occasionally in the neck and abdominal regions. Esophageal duplication cyst is usually diagnosed in early childhood because of symptoms related to bleeding, infection, and displacement of tissue surrounding the lesion. We recently encountered a rare adult case of esophageal duplication cyst in the abdominal esophagus. A 50-year-old man underwent gastroscopy, endoscopic ultrasonography, computed tomography, and magnetic resonance imaging to investigate epigastric pain and dysphagia that started 3 months earlier. Imaging findings suggested esophageal duplication cyst, and the patient underwent laparoscopic resection followed by intraoperative esophagoscopy to reconstruct the esophagus safely and effectively. Histopathological examination of the resected specimen revealed two layers of smooth muscle in the cystic wall, confirming the diagnosis of esophageal duplication cyst.
RESUMO
Incarcerated inguinal hernia is often encountered by surgeons in daily practice. Although rare, hernial reduction en masse is a potential complication of manual reduction of an incarcerated hernia. Manual reduction was performed in a case of Zollinger classification type VII (combined type) hernia in which the indirect hernia portion included an incarcerated small intestine. This procedure caused hernial reduction en masse, but this went unnoticed, and the remaining portion of the direct hernia in the inguinal region was treated surgically by the anterior approach. Because the incarcerated small bowel that had been reduced en masse was not completely obstructed, the patient's general condition was not greatly affected, and he was able to resume eating. Twenty days after surgery, he developed sudden abdominal pain as a result of gastrointestinal perforation. When performing manual reduction of an incarcerated hernia in cases after self-reduction over a long period, the clinician should always be aware of the possibility of reduction en masse.
